Abstract: A systematic experiment relating to the electrochemistry of oxygen ion transport in slag has been studied in lab. An equivalent circuit has been used to describe ion transfer between metal and slag in this paper and a kinetic model with electrochemical characteristic representing oxygen ion immigration has been worked out. The different experimental phenomena can be explained generally by this model. It can be seen that the theoretical results are in good agreement with experiments. The comparison of experimental data with model calculation proved that the electrochemical model is right.
Key words: metal-slag reaction; oxygen ion; electrochemical model
